93 Rx-7 PLZ HELP!

Hey, wrong place for this, but more ppl look here, so i need some advice. my frien is looking at a 93 Mazda Rx-7, an we're both VERY new to rotary motor cars. i kno how they work an all, but we're goin to check one out tomo, an i was wondering if u guys knew of anything to look out for in those cars taht was diff. any advice/suggestions are great, so thx ahead of time.

btw...its got 35k on a REBUILT motor, outside appears to be clean tho. thx again.

Other than I can't stand rotary's and they are not very reliable in the long term they do offer great weight saving and simplicity.

You would be very wise to have the compression checked. Apex seals are shockers for dying. If it is a turbo car I would inspec the intercooler for oil as that is a sign the turbo seals are going. As far as the rest no idea mate.

If the engine has been recently rebuilt and it's that recent of a car (FD generation) then you'll have few to no problems. The RX-7's woeful reliability reputation is solely undeserved. With simple PREVENTIVE maintenance you can have a rotary that'll out last most any reciprocating engine. SCCA competitors have been building the old 12A from the 1st gen RX-7 to make NA 220hp engines that last for at least 400 track hours before needing any internal work, and the 13B is that much more reliable.

Change the oil religiously! NO WAITING A FEW MILES! Plus be careful with the turbos, their apex seals go a lot easier than the NA's, especially when you start piling on boost.

Beyond that, you've got nothing really to worry about. The rotary is one of the true marvels of automotive engineering. Don't let its exotic layout prevent you from enjoying its wonderful capabilities.

ah...sweet. we weren't gonna let it scare us away from the car, jus needed to kno anything to look out for. i'll check for the oil on the intercooler, an have him take it for a compression check. i do agree they are marvel's of cars...an imma be jealous of the guy :D . but i'll make sure he does his oil changes/tune ups, when they're supposed to be done. if he doesn't...i'll beat him.

:hehehe: we asians kno how to get down :D

Where are you guys located state and city if possible. I was wondering because I have a friend in vegas who is trying to get rid of his Mr2 a Toyota supra and his Rx-7. The rx-7 is a 95 I think not sure will have to find out.

LOL!:eshooter:

Like Octagon said, the horrible reliability issue that seems to follow rx7s round is undeserved. The 13b however is a high maintenance engine, it will demand regular oil changes often and you will need to have the engine rebuilt (1500-2000$) about every 75K miles just so you won't have any worries.

FD rx7 is definetely my favorite car from Japan, R34 can suck me.

In my experience you asians know how to fall down very well.

hahahhahahha...man...don't get me started on U ppl j/k :hehehe: (sorri if i offend anyone, is all in joke)

im up here in seattle washington, so it's pretty long drive from vegas. we jus test drove the car today. u gotta love power throughout the band an not jus when u hit vtec. ran great, but shitty interior. learned that the 93's had a recall about the interior, but this one hadn't had it but...ah well. the motor was in good condition, checked the intercooler for oil, an found none. we'll take it to get a compression check soon, cuz we met up too late, an shops were closed. seems to be a pretty nice car, an i'll let u guys kno if he gets it.

so jealous :D

haha.. that goes both ways. :p





Krn: goodluck with the rx7!

rx-7 give me nightmares. i never want to work on one ever again. they are one of most difficult cars to ever work on. just to change plugs and wires, you need to remove the entire throttle body. also to change vacuum lines you need to remove the whole throttle body alone with the intake manifold. plus, argh, forget it, that car is just a nightmare to work on.

wussssss:hehe:

j/k

see steel you got a FC. its easier to work on a FC. the FD's engine bay is sooo cramped, there you have to take almost everything out to change the smallest things. not cool at all.

you're not allowed to use synthetics in a rotary because of one reason it burns the oil it works almost nothing like a normal turbo engine.
Best thing to look for is faulty Temp sensor and over heating problems.

hence the j/k in my post ;)

But even then, FC's (espt TII's) are not the funnest things to work on.

Oh, and a really good reliability mod to do is to take out your oil injectors and run premix in your gasoline. Then you can run synthetic oil in the engine. All around makes for a happier engine.

oh, and this might be helpful if your lokin on buying a used rex. http://www.rx7turboturbo.com/robrobinette/buyaused.htm

sweet link...lots of information. thx. :D
